I hope you don't mean this literally. There are millions of humans without the innate capacity to reason. Not to mention those who are too young to have developed it.
I don't propose to make a meal out of little children, whose rational capacity is not fully developed, nor do I want to purchase the still-living body of Ronald Reagan so that I can turn it into a floor-lamp. Those of us who are capable of reason are usually quite prepared to extend the concept of rights to all of our species.
